Open source firmware for the SMA-Q2 smart watch

sma-q2-oss's Issues

Settings App

New Feature Idea:

Provide an app to change some configuration directly on the watch, e.g. vibration length, background light intensity, BLE pairing information

Nice error screen! Oh F:4001,0,20004A94

Red background, message:

F:4001,0,20004A94
E:0x3

revision e4d6f2c

Notification scroll

New Feature Idea:

Make scrolling through a long notification text possible

firmware builds with no errors but resulting zip makes the watch go into an error mode.

Error displayed on red screen:

F:4001,0,200049DC
E:0x3

Every now and then I get a brief flash of a blue screen with the word "Blue" about a third of the way down the screen then back to the error.
I can get back to the OTA mode using the Volume up + volume down + left button.

I have no background with nrf and middle of the road programming skills.

Any plans to port to other SMA models?

Any possible candidates? which models could be modded?

Notification responses

New Feature Idea:

Define a basic set of responses to be sent directly from watch in the notification menu.

Alarms

New Feature Idea:

Establish some form of alarms, either configurable through gadgetbridge (like on some buttonless smart trackers) or full featured setting on watch directly

Notification wordbreak

New Feature Idea:

Make the text in notifications break on word borders and not just anywhere

Pairing issue

hi,

this is a very promising project and id like to contribute if possible, thanks for the great work!

i struggle to pair the sma q2 and various android phones (8.1.0) via the forked gadgetbridge, maybe you have a hint or two on how to get it working?

what i did:

• compile firmware (see PR #5)
• put watch into DFU mode and flash resulting firmware via D6Flasher
• compile forked gadgetbridge
• install generated debug apk via adb to phone (since the release version has no certificates)
• reboot phone
• try to add watch in gadgetbridge
• result: gadgetbridge never sees the sma q2

the bluetooth menu did see the watch and out of desperation i paired it with the phone directly. got asked to very the pins and paired it. unfortunately, gadgetbridge still didnt see the watch (i unchecked the option to hide paired devices).

now unfortunately, i deleted the pairing on the phone but then noticed, the watch will reject further pairing attempts right away.

as a last resort, i went back into DFU mode and reflashed the firmware. unfortunately, that did not restore the initial pairing capabilities.

do you have any tips from here on?

id like to leave the watch closed if possible, but i could also open it to reach some jtag pins or whatever is needed.

thanks!

Linker error on first build

Hello,

I'm setting up the environment for local development, and I stumbled on an error on the first build.

After downloading and setting up the nRF SDK, patching the necessary files and configuring Makefile.posix, the linker yells at me when trying to run make.

The error shown is as follows:

gcc version 9.3.1 20200408 (release) (GNU Arm Embedded Toolchain 9-2020-q2-update) 

It looks like an error directly in the SDK which is trying to redefine two functions (_write and _read) in libraries/uart/retarget.c.
Any hints on what might be happening?
